Hadn't thought about the emergency acceleration issue--I thought that if you floored it the vehicle would realize the situation and kick in the ICE. I'm a little surprised that's not the case, since the ICE kicks in under all kinds of other situations (Max Defrost, Defrost without face level vent, and of course battery temperature excursions, excessively cold temps, and full battery need for engine braking.) Looking forward to your findings on the relative scales for the gauges.
I had one of those unanticipated errands this evening where I hadn't charged the car overnight. Pulled into the driveway on empty/EV+ after a grocery store run, but managed to not start the ICE. Luckily it was all back roads on the way home and I was able to be rather leisurely, and made sure not to exceed the ICE start threshold once EV Now was no longer available. I did run the engine this Sunday since I had passengers, and it was a dreary cold day that called for climate control.
I had a hard braking event this morning trying to pull onto the main road and seeing traffic late. I'm glad to say the tires stuck and stopped the car quickly.
